PIPE VISE.

Application filed February 6, 1826; Serial No. 8%,415.

In performing work upon pipes, tubes, or

rods of brass, nickel plate, copper, bronze, and other similarly expensive and valuable material. it is essential to provide a means for holding'such articles in a vise, which will not cut, mar, scratch or otherwise injure the surface or the material operated upon.

To this end I have devised my present novel vise, which consists in a pair of clamping jaws, hinged together atone end, and having a plurality of cooperating graduated arcuate clamping depressions or recesses therein, these clamping depressions being constructed and arranged to hold pipes, tubes or rods of greatlyvarying sizes and dial eters. These depressions are smooth on their interior faces, and thus effecta smooth grip on the article held thereby, without scratching, mar-ring or injuring the same, and hence the extreme importance of my novel clamping jaws, and their applicability to this type of work. will be greatly appreciated by those skilled in the art.

A furt ier important feature of my present invention is the applicability of my novel vise to practically any work support, such as a bench, table, or even to a pole, post or the like, having a rounded contour.

In order to insure a firm seating of my novel vise on any work support, I provide a three-pointsupport, thus eliminating the diiiiculties to be encountered in a rough table or bench.

I believe that my novel vise is new, and I wish to claim the same broadly herein.

A further feature of my novel vise is the ease and quickness with which the same may be operated. my novel handle and clamping arrangement permitting almost instant opening or closing of the vise.

Further features of the invention, novel combinations, details and advantages will be hereinafter more fully pointed out and claimed.

Referring to the drawings, illustrating a preferred embodiment of my present invention,

Fig. 1 is a side elevation;

Fig. 2 is a top plan View;

Fig. 3 is a rear elevation;

Fig. 4 is a front elevation; and

Fig; 5'is a cross-sectional View on the line 5-5 ofFig. 1,

As shown in the drawings, my present novel vise comprises a pair of aws 1 and 2, the 2 preferably forming an integral part of the base 3, which base has a threepoint support. comprising the bosses 1 at the rear, 5 at the front and G offset approximately at the center of the base. The jaw 1 is hinged to the jaw 2 by a bolt 7 and nut 8. The'jaw 1 terminates at the rear in a. lug or stop 9 which is constructed and arranged to strike against the surface 11 of the web to prevent too wide an opening of the aw 1.

At the front and rear of the base 3 are provided holes or apertures 12, 12, for securing the base to the work support. The bosses 6 also terminate in a slot 13 for securing to the work support, whether table, bench, pole, post or the like. At the frontof the vise a stem 14 is pivoted at 15, this stem being threaded at 16 as shown, and having a collar 17 threaded thereon. A handle 18 is pivoted to the collar 17 by pivot pins 19 through the arms 20 of the handle 18. hen in closed position, as illustrated in the drawings, the stem 14 is positioned in a slot 21 in bracket arms 22. When it is desired to open or separate the. jaw 1 from the jaw 2, the handle 18 is rotated approximately one complete turn, thus threading the collar 17 upwardly on the threaded end 16 of the stem 1%, and moving the collar 1.7 suiiiciently above the bracket arms 22 to permit the stem 14 to be drawn forwardly by the handle 18, thus releasing the jaw 1, and enabling same to be, opened for the insertion and reception of the rod, tube, pipe or article to be clamped in the vise. hen the article is thus received, the jaw 1 is closed, stem 14 forced back into the slot 21, handle 18 and collar 17 threaded one turn down on the threaded end 16, and the vise jaws are firmly closed and the article held therein securely clamped in position.

In the jaws 1 and 2 are a plurality of graduated arcuate recesses or depressions 23, 24:, 25, etc., eight of these recesses being herein illustrated, although I may utilize any number or size. Dividing these recesses 23, 24C and 25 are cross ribs or webs 26, 27, 28, etc. The interior faces of these depressions are smooth and even, thus providing a firm clamp on any object held therein, without marring or injuring the same In the jaw 1 I have providedpreferably a plurality of longitudinal reinforcing ribs 29, and a cross web 30, for strengthening purposes. The lower jaw 2 is also preferably reinforced in the same manner.

If desired I may mark or indicate the respective sizes of piping or tubing to be received by the various recesses.

As indicated in Fig. 5, the base is forinee arcuate, as shown at 31, to permit application of the vise to a pole or post,or other support having a rounded contour and insuring a firm seating of the vise thereon, and may be secured thereto by a chain;

The operation of my novel vise will be readily understood. The vise being secured on a suitable work support, and it being de sired to clamp a pipe, the handle 18 and collar 17 are threaded one turn off the end 16 of the stem 14, and pulled forward, thus disengaging the jaw l, which is then raised upwardly, to its limit if desired, too great an opening being prevented by the lug 9 striking on the face 11 of the web 10. A pipe or tube is then inserted in the recess adapted to receive same, the jaw 1 lowered, and the stem 14- forced back into the slot 21 and collar and handle threaded to clamping position, preferably approximately one complete revolution of the collar 17. The pipe or other article is then securely clamped in position and ready to be operated upon. ,7

I believe that my novel vise, as above described, is new, and I wish to claim the same broadly herein.

l ihile l have necessarily described my invention somewhat in detail, it will be appreciated that I am not limited thereto, but

may vary the size, shape, and arrangement of parts within reasonably wide limits without departing from the spirit of the invention.

J My invention is further described and defined in the form of claims as follows:

1. In a vise of the kind described, a base having a jaw integral therewith, a movable jaw hlnged to the first jaw, reinforcing webs extending longitudinally of each jaw each of said jaws having arcuate depressions cooperati ig to form graduated pipe clamping recesses, and a projecting lug at the rear said movable jaw to limit theopening thereof, said base having three supporting portions, formed arcuate to permit application to a rounded support said base being also provided with means to apply said vise to a flat surface. j

2. In a vise of the kind described, a base having a jaw integral therewith, a threep'oint support for said base, a movable jaw hinged to the first jaw, reinforcing webs extending longitudinally of each jaw each of said jaws having arcuate depressions 00- operating to form graduated pipe clamping recesses, a projecting lug at the rear of said niovable jaw to limit the opening thereof, a stem pivoted at the front of said base, a collar threaded on said stem and a yoked handle pivoted to said collar, said stem being adapted to engage a slot in the front of said movable jaw and lock said jaw in clamping position.

3. In a vise of the kind described, a base having a jaw integral therewith, threepoint arcuate support for said base, a movable jaw hinged to the first jaw, reinforcing webs extending longitudinally of each jaw each of said jaws having arcuate depressions cooperating to form a series of pipe clamping recesses graduated from the hinged portion forwardly, a projecting lug at the rear of said movable jaw to limit the opening thereof by contacting with a web on said base, and means to clamp said jaws in engaging position.

y In testimony whereof, I have signed my name to this specification.
